Ch 12 · Lesson 16

Esperanto slang: mojosa, -aĉ- and krokodili

is cool, o is a cur, and is slipping into your own language at an Esperanto event: the words the community uses on itself.

The short version

means cool, and it has a birthday

!

The new song is seriously cool!
Why?

is cool in the sense of great, never cold. It was coined in November 2003 at a youth seminar in Hungary from the initials of , and : MJS, read as , plus the adjective -a. It is not in PIV, but younger speakers use it everywhere, usually boosted with .

Add -aĉ- to make anything rotten

!

What a rotten day!
Why?

The suffix -aĉ- turns almost any root contemptuous. is a dog, o a cur; is a house, o a hovel; is to sing, kantaĉi to sing badly. On its own it is an adjective, , lousy. It is the most productive insult in the language, and every speaker understands a new one at once.

The word for lapsing out of Esperanto:

krokodilu!

Stop speaking your national language - back to Esperanto!
Why?

At any Esperanto gathering, slipping into your own national language instead of Esperanto is called , and it is the community's own running joke about itself. Knowing the word - and that it gets called out with a laugh, not a lecture - means you get the joke instead of just parsing the sentence next time you see it in a group chat.

slang is the layer of words speakers use about themselves. is cool, is slipping into your own language, kabei is quitting for good. None is in a phrasebook, and all of them are in the group chat.

mojosa: cool

means cool in the sense of great, not cold. It is built from initials: moderna, na, stila (modern, young, stylish), MJS, padded with vowels and given the adjective -a. It was coined in November 2003 at a youth seminar in Söjtör, Hungary.

It takes every adjective ending, and - and -e work on it as on any adjective:

FormEnglish
cool
cool (plural)
auncool
coolly, in style
  • ! - The new song is seriously cool!

, from the suffix --, is the usual booster. The word is not in PIV, the big reference dictionary, and an older speaker may not know it: that is how slang travels.

  3. mojosa
  4. ege mojosa

-aĉ-: rotten, and sal for hello

affixWhat do the colours mean?

The suffix -- makes anything rotten. It works on almost any root, which makes it the most useful insult in the language:

PlainWith --English
a cur
a hovel
foul weather
kantaĉito sing badly

On its own it is an adjective: , lousy. ! - What a rotten day!

At the friendly end, is the casual short form of , hello, common in chat and among friends. Keep for anyone you do not know.

krokodili and the reptile family

Put twenty Esperantists in a room and some will share a national language. Speaking it there is , to crocodile: a crocodile, , turned into a verb.

  • a crocodilea crocodile
  • krokodilu! - t crocodile! (Speak Esperanto!)

It is called out with a laugh, usually by someone who was doing it an hour earlier. Where the word comes from is not settled: several stories are told with confidence, and none is proven.

The community has built a joke family on it, sorted by whose language you are speaking. Definitions vary from speaker to speaker; these are the common ones:

VerbYou speak
your own language
aligatoria language native to others, not to you
kajmania language native to nobody present
gaviali, where another language would serve
Your own languageNobody’s own language
  1. krokodili
  2. aligatori
  3. kajmani

is the one everyone knows; the rest are mostly jokes.

Going further: kabei: the man who became a verb and the rest of the guide, when you want them. This lesson does not need them.
